I once learned to solve the cube, because I considered myself decently smart so I thought I just had to do it. "Smart kids can solve the cube".
I solved one but it took a lot of time.

Years later I got some Internet and saw a lot of people solving it in very short time, and I was intrigued how someone could be that much smarter than me. Then I discovered the first people that solved it without looking, and that's where I realized there had to be something fishy going on, so I looked it up.

I was very disappointed when I discovered the solution is an algorithmic one. Most of the time you don't even have to look, nor understand how the cube works, you just follow the memorized steps.

That's where I basically lost interest.

But yeah, being quick enough to do it for three cubes, while juggling them? That's some serious skills there. Impressive!
